DPSing as a healer

[Supersun]

T On PS4 there are 8 available, that doesn't require pressing multiple buttons to gain access to extra hot keys.

Err, I use a controller and you have access to 32 through just the use of the L2 and R2 triggers. You have 8 for L2, you have 8 for R2, you have 8 for L2+>R2, and you have 8 for R2+>L2, (and if you really needed it you could set up an L1 toggle for an additional L2 and R2 for an extra 16).

Are there any classes that need more than 32 to perform optimally?
